Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Hardy-Weinberg Principle

Hardy-Weinberg Principle

Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

Background:

Haplotype reconstruction from fragmented, error-prone DNA sequences is a complex computational problem.
Existing methods face challenges in accuracy and efficiency when dealing with noisy sequence data.

Purpose of the Study:

To develop a novel heuristic algorithm for accurate haplotype pair construction.
To minimize errors during haplotype reconstruction using a minimum error correction approach.

Main Methods:

Introduced the Heuristic Minimum Error Correction (HMEC) algorithm.
HMEC employs a gain measure to iteratively search for optimal solutions.
Analyzed time complexity as O(m^3 k) for an m x k SNP matrix.

Main Results:

HMEC demonstrated superior accuracy and reduced running time compared to existing methods.
Performance validated on both simulated and real-world genomic datasets.
An alternative gain measure was proposed to further optimize computational efficiency.

Conclusions:

The HMEC algorithm provides a robust and efficient solution for haplotype reconstruction.
This method significantly advances the ability to accurately determine haplotypes from fragmented DNA.
